That is not right.
While you cannot use Turbotax for paid preparation, you are under zero obligation to pay for Intuit's pro series of tax prep software. You are free to use any professional tax software.
The comment that you have to must be removed as Intuit would be violating antitrust law to state you must.
You also need to be careful.
A paid preparer has to be paid to use their PTIN on someone else's taxes.
Another issue is that TurboTax has free Federal filing while ProSeries we all have furnish our own E-filing pin. I bring this up because Intuit does not advertise this fact.
